Product Introduction

The VIP1-1B-03 is a single phase 3A EMI power filter engineered for 115/250VAC and 50/60Hz power networks. Built with low leakage current design and a broad operating temperature span from -25℃ to 100℃, this single stage filtering device effectively attenuates both common mode and differential mode electromagnetic interference carried by power lines. It has completed rigorous high voltage withstand and insulation resistance verification, ensuring dependable and safe long term performance across varied industrial working conditions.

Application & Purpose

This industrial EMI filter is broadly compatible with PLC systems, servo drives, frequency inverters and other industrial automation machinery. It works to remove high frequency power noise and harmonic distortion on the supply side, prevent unexpected faults and abnormal shutdowns of precision equipment caused by power interference, and assist finished products in passing standard EMC certification tests so that the entire production system can maintain continuous stable operation.

FAQ

1. Q: What is the difference between single phase and three phase power filters A: Single phase filters are designed for L and N line systems and are commonly used in small to medium industrial equipment. Three phase filters handle three live wires plus neutral and earth and are suitable for high power machinery and industrial drive systems.
2. Q: How does ambient temperature affect the performance of an EMI filter A: High ambient temperature accelerates aging of internal capacitors and insulating materials. This filter supports operation up to 100℃, but proper ventilation and avoiding installation near heat sources will extend its service life and maintain stable attenuation.
3. Q: What should be checked before installing a new power filter A: Confirm the rated voltage and current match the equipment, verify the earthing bar is clean and conductive, ensure input and output cable routes are separated, and check that the filter housing has enough space for heat dissipation.
4. Q: Can a power filter reduce harmonic distortion caused by inverters A: Yes. EMI filters attenuate high frequency switching harmonics generated by inverters and servo drives. For severe low frequency harmonic issues, additional harmonic reactors or active power filters may be required alongside the EMI filter.
5. Q: What safety certifications should an industrial power filter carry A: Products sold in China should carry CCC certification. For export markets, CE certification is required for the European Union and UL certification for North America. Certified products ensure compliance with insulation, leakage current and fire safety standards.
